This paper is treated Geomet- ridae collected on the Sakhalin Island in 2000 during the field survey of Zoological Museum, Far Eastern State University (Vladivostok) supported by Sakhalin Energy Investment Company LTD. All specimens of Geometridae were collected by A.V. Propletkin and deposited in Institute of Biology and Soil Science (Vladivostok). DISCUSSION 238 specimens belonging to 56 species of Geometridae have been collected in 15 localities (Fig. 1). The list of the species with collecting sites and number of specimens is given in Table 1. The species are arranged according to their capturing from south to north. Two species (double asterisked) were recorded for Russia for the first time and 5 species (single asterisked) were firstly mentioned for Sakhalin (Table 1). Among them Biston betularius and Lomographa bimaculata are very common through the Palaearctic region. This newness emphasises an insufficiency of investigation of the geometrid moths on the Sakhalin Island. Parectropis similaria japonica is given in the current treatment, but very likely it is a well- separated species. Additional material is needed for solving of this problem. The boreal species of Geometridae are dominated in most collecting sites. The species with East Asian nemoral range are presented in the localities from 1 to 5 (approximately up to 49°N), about one-third of them are associated with Picea- Abies forests and connected trophically with coniferous trees (Garaeus mirandus, Protoboarmia faustinata, Semiothisa fuscaria, Myrteta unio, Nipponogelasma lucia). Only one East Asian species, Alcis medialbifera, was recorded from central and northern parts of the Island (localities 10, 12, 13), probably because of more later flying of imago. This species is nocturnal and trophically connected with coniferous trees but in the localities 10 and 13 has been collected in the daytime (8 and 14 specimens respectively). Almost widely distributed boreal transpalaearctic species were collected in the central part of Sakhalin (localities 6-11, approximately up to 50°N). Only arctic-boreal geometrid moths were found in the more northern localities (13, 14, 15). The study show a changing of the geometrid species composition on Sakhalin from south to north. The number of transpalaearctic boreal and arctic-boreal species increased northwards. Transpalaearctic boreal species predominate in Sakhalin geometrid fauna. 2 Fig. 1.
